What will you mostly use it for?
In gaming and travel, the keyboards are effectively tied, sharing the same layout, connectivity, and polling rate. The B87 wins for programming and modding due to its QMK/VIA support and multi-layer foam structure. The Y87's aluminum case and dedicated knob give it the edge in office and content creation use cases where build quality and a physical control are prioritized. Your choice will largely depend on whether deep software customization or a premium chassis with a knob matters more.
It's a tie
- Both offer 1000 Hz polling rate. B87 vendor description states a 1000 Hz polling rate. Y87 metadata also shows 1000 Hz polling rate.
- Both offer NKRO and hot-swappable switches suitable for gaming.

Yunzii B87 vs Y87: your questions
The Y87 uses an aluminum case, which typically provides a more premium feel and greater rigidity than the B87's ABS plastic case. However, the B87 includes a soft-touch wrist rest and a multi-layer foam structure for sound dampening, which can also contribute to the overall user experience.
Only the Yunzii B87 supports QMK and VIA. The vendor description for the B87 explicitly states it is a QMK/VIA custom keyboard, allowing for web browser-based key remapping, macro creation, and lighting effects. The Y87 does not support QMK or VIA.
The B87 has a larger 4000mAh battery, while the Y87 has a 3000mAh battery. The Y87's vendor description claims its battery can last up to 350 hours, but the B87's metadata does not provide an estimated battery life figure.
No, only the Yunzii Y87 includes a metal knob. The Y87's vendor description states it has a solid silver color knob for switching between Wireless, Bluetooth, and Wired connection modes. The B87 does not have a knob.
The B87 is designed with a gasket mount structure and 5 layers of padding, including PE Sandwich Foam, IXPE Switch Pad, PET Sound Foam, Switch Foam, and Silicone Bottom Pad. This construction is intended to reduce noise. The Y87 uses sound-absorbing silicon, but the B87 has more dedicated padding layers.
Yes, both keyboards are hot-swappable. The manufacturer states both the B87 and Y87 support 3-pin and 5-pin switches. This allows you to install a wide range of aftermarket mechanical switches without soldering.
Both keyboards use PBT keycaps. The B87 uses Dye-Sublimation PBT keycaps in an MOA profile, while the Y87 uses PBT Double-shot keycaps. Both materials are known for being durable and resistant to developing a shiny finish over time.
Yes, both keyboards have Mac/Win support. The Y87's vendor description says it works with Win, iOS, and Mac systems, and you can switch modes by pressing FN + I (iOS), O (Mac), or P (Win). The B87's metadata also lists Mac/Win support.
The Y87 is likely lighter; the B87's published weight is 1128g, while the Y87's weight is not provided in the data. Both are 80% 87-key layouts, making them relatively compact. Their portability scores from the data are very similar (73.1 for B87, 73.7 for Y87).
No, the Y87 does not include a wrist rest. The B87 comes with a complimentary soft-touch wrist rest, which is explicitly mentioned in its vendor description. You would need to purchase a wrist rest separately for the Y87.
